Application February 2,

This invention relates to disposable cooking utensils, more particularly to disposable broiling or roasting trays or pans made of aluminum foil.- The object of the invention is the provision of a practical and inexpensive broiling or roasting 5 tray or pan made of aluminum foil which, despite being made of such foil, is sufiiciently rigid for practical use, and which provides for supporting Whatever is being broiled orroasted above the bottom of the pan.

In general, the utensil of this invention consists of a rectangular pan formed from a blank of aluminum foil having a flat bottom and upwardly bent side and end walls. The pan is formed with integral reinforcing ribs extending 15.

parallel to one another throughout the length of the pan from the upper edge of one end wall of the pan to the upper edge of the other, each of the ribs having a portion in the form of a ridge extending upward from the bottom of the pan and extending from near one end of the bottom to near the other end of the bottom, and flattened end portions extending from the ends of the ridge up to the upper edges of the end walls. Other features will be in part apparent and in part pointed out hereinafte The invention accordingly comprises the elements and combinations of elements, features of will be exemplified in the structures hereinafter 39 described, and the scope of the application of which will be indicated in the following claim.

In the accompanying drawing, in which one of various possible embodiments of the invention is illustrated,

Fig. 1 is a perspective view of a stack of pans of this invention, with parts broken away;

Fig. 2 is a vertical longitudinal section taken on line '22 of one of the pans shown in Fig. 1;

Fig. 3 is a vertical transverse section taken on 40 line 3-3 of one of the pans shown in Fig. 1; and, Fig. 4 is an enlarged fragmentary horizontal section taken on line 4-4 of Fig. 3.

Similar reference characters indicate corresponding parts throughout the several views of the drawing.

conveniently nested for purposes to be mentioned walls 5 and 1, respectively. The corners of the pan are closed by folding as indicated at 9. The 5 1951, Serial No. 209,003 1 Claim. (Cl. 220-72) pan is formed extending parallel to one another throughout the length of the pan from the upper edge of one end wall 1 to the upper edge of the other end wall 7.

Each rib has a portion in the form of a ridge of generally inverted V-shape in cross section extending upward from the flat bottom 3 throughout a portion of the length of the bottom from near one end of the bottom to near the other end of the bottom, the V-shaped ridge portion of each rib being designated in its end portions in the end walls 1 of the pan as indicated at I 5. The V-shaped ridge portion [3 a particularly heavy cut of meat is to be broiled or roasted, a nested stack of pans, such as shown in Fig. 1, may be used. After such use, only the top pan need be discarded. A large number of the pans may also be packaged and sold and kept of the pan, as is desirable.

In manufacturing the pans, it is contemplated that they be made by forming V-shaped ribs or PATENT OFFICE with integral reinforcing ribs ll I3, and each rib is flattened 3 the blank makes it possible readily to bend up the end walls, the foil being more readily bent where the ribs are flattened.

While the drawings illustrate all the ribs H extend from the upper edges of the end walls to the fold lines where the end walls are folded up each consisting of an integral plait-like portion or the foil flattened upon itself on the inside of the as being flattened with regularity (i. e., all the end 5 end wall, each rib also having a portion in the portions of the ribs are flattened in exactly the same manner), it will be understood that the flattening may be irregular or indiscriminate. For example, instead of having all the ribs folded in cross secti tom of the pa of the bottom form of a ridge generally of inverted V-shape on extending upward from the botn and reaching from near one end to near the other end of the botdown toward one. side of: the pan (see Fig. 4), tom; and each rib also having transition sections some may beflattened' toward one side and sometoward the other, or each rib may have part folded toward one side and part toward the other.

In view of the above, it will be seen that the.

tions, said ally from the extending from the ends of the V-shaped ridge portion to the lower ends of the plait-like portransition sections developing graduinverted V-shape or the ridge porseveral objects or the invention are achieved and tion to the flattened plait-like form of the end other advantageous results attained.

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the. accompanying. drawing shall be interpreted as illustrative and not in alimiting sense.
